STATE STREET CORPORATION
EARNINGS RELEASE ADDENDUM
RECONCILIATIONS OF OPERATING-BASIS (NON-GAAP) FINANCIAL INFORMATION

In addition to presenting State Street’s financial results in conformity with U.S. generally accepted accounting principles, referred to as GAAP, management also presents results on a non-GAAP, or "operating" basis, as it believes that this presentation supports meaningful comparisons from period to period and the analysis of comparable financial trends with respect to State Street’s normal ongoing business operations.
Management believes that operating-basis financial information, which reports revenue from non-taxable sources, such as interest revenue from tax-exempt investment securities and processing fees and other revenue associated with tax-advantaged investments, on a fully taxable-equivalent basis and excludes the impact of revenue and expenses outside of State Street's normal course of business, facilitates an investor's understanding and analysis of State Street's underlying financial performance and trends in addition to financial information prepared and reported in conformity with GAAP. Non-GAAP financial measures should be considered in addition to, not as a substitute for or superior to, financial measures determined in conformity with GAAP.
The accompanying materials present financial information prepared on a GAAP as well as on an operating basis; accordingly, this earnings release addendum provides reconciliations of operating-basis financial measures. The following tables reconcile operating-basis financial information presented in the accompanying earnings release to financial information prepared and reported in conformity with GAAP.

Regulatory Capital

The accompanying materials present capital ratios in addition to, or adjusted from, those calculated in conformity with applicable regulatory requirements. These include capital ratios based on tangible common equity, as well as capital ratios adjusted to reflect our estimate of the impact of the relevant Basel III requirements, as specified in the July 2013 final rule issued by the Board of Governors of the Federal Reserve System, referred to as the Basel III final rule. These non-regulatory and adjusted capital measures are non-GAAP financial measures. Management currently calculates the non-GAAP capital ratios presented in the news release to aid in its understanding of State Street’s capital position under a variety of standards, including currently applicable and transitioning regulatory requirements. Management believes that the use of the non-GAAP capital ratios presented in the accompanying materials similarly aids in an investor's understanding of State Street's capital position and therefore is of interest to investors.

The common equity tier 1 risk-based capital, or CET1, tier 1 risk-based capital, total risk-based capital and tier 1 leverage ratios have each been calculated in conformity with applicable regulatory requirements as of the dates that each was first publicly disclosed. The capital component, or numerator, of these ratios was calculated in conformity with the provisions of the Basel III final rule. As of June 30, 2014, September 30, 2014 and December 31, 2014, the total risk-weighted assets component, or denominator, used in the calculation of the CET1, tier 1 risk-based capital and total risk-based capital ratios were each calculated in conformity with both the advanced approaches and transitional provisions of Basel III, as the case may be. As of March 31, 2015, June 30, 2015 and September 30, 2015, the total risk-weighted assets component, or denominator, used in the calculation of the CET1, tier 1 risk-based capital and total risk-based capital ratios were each calculated in conformity with the advanced approaches and standardized approach provisions of Basel III, as the case may be.

The tangible common equity, or TCE, ratio is an additional capital ratio that management believes provides context useful in understanding and assessing State Street's capital adequacy. The TCE ratio is calculated by dividing consolidated total common shareholders’ equity by consolidated total assets, after reducing both amounts by goodwill and other intangible assets net of related deferred taxes. Total assets reflected in the TCE ratio also exclude cash balances on deposit at the Federal Reserve Bank and other central banks in excess of required reserves. The TCE ratio is not required by GAAP or by banking regulations, but is a metric used by management to evaluate the adequacy of State Street’s capital levels. Since there is no authoritative requirement to calculate the TCE ratio, our TCE ratio is not necessarily comparable to similar capital measures disclosed or used by other companies in the financial services industry. Tangible common equity and adjusted tangible assets are non-GAAP financial measures and should be considered in addition to, not as a substitute for or superior to, financial measures determined in accordance with GAAP or other applicable requirements. Reconciliations with respect to the calculation of the TCE ratios are provided on page 14 of this earnings release addendum.

The following table presents State Street's regulatory capital ratios and underlying components, calculated in conformity with applicable regulatory requirements as described above.

Provisions of the Basel III final rule, issued in July 2013, become effective under a transition timetable which began on January 1, 2014. We have used the advanced approaches provisions provided in the Basel III final rule to calculate our regulatory capital ratios beginning with the second quarter of 2014. Beginning with the first quarter of 2015, we began to also use the standardized approach provisions provided in the Basel III final rule to calculate our regulatory capital ratios.
Prior to the first quarter of 2015, the lower of our regulatory capital ratios calculated under the Basel III advanced approaches and those ratios calculated under the transitional provisions of Basel III were applied in the assessment of our capital adequacy for regulatory purposes. Beginning in the first quarter of 2015, capital ratios calculated under the Basel III standardized approach replaced the transitional ratios in the assessment of our capital adequacy for regulatory purposes.
The following tables reconcile our fully phased-in estimated pro forma CET1 ratios calculated in conformity with the Basel III final rule, as described, to our CET1 ratios calculated in conformity with applicable regulatory requirements as of the dates indicated.

RECONCILIATIONS OF SUPPLEMENTARY LEVERAGE RATIOS

In 2014, U.S. banking regulators issued final rules implementing a supplementary leverage ratio, or SLR, for certain bank holding companies, like State Street, and their insured depository institution subsidiaries, like State Street Bank. We refer to these final rules as the SLR final rule. Under the SLR final rule, upon implementation as of January 1, 2018, (i) State Street Bank must maintain an SLR of at least 6% to be well capitalized under the U.S. banking regulators’ Prompt Corrective Action framework and (ii) if State Street maintains an SLR of at least 5%, it is not subject to limitations on distribution and discretionary bonus payments under the SLR final rule. Beginning with reporting for March 31, 2015, State Street is required to include SLR disclosures with its other Basel disclosures.
Estimated pro forma fully phased-in SLR ratios as of September 30, 2015, June 30, 2015 and March 31, 2015 are preliminary estimates by State Street (in each case, fully phased-in as of January 1, 2018, as per the phase-in requirements of the SLR final rule), calculated based on our interpretations of the SLR final rule as of October 23, 2015 and as applied to our businesses and operations as of September 30, 2015, June 30, 2015 and March 31, 2015. Estimated pro forma fully phased-in SLR ratios as of December 31, 2014 are preliminary estimates by State Street, calculated based on our interpretations of the SLR final rule as of January 23, 2015 and as applied to our businesses and operations as of December 31, 2014.
The following tables reconcile our estimated pro forma fully-phased in SLR ratios as of September 30, 2015, June 30, 2015, March 31, 2015 and December 31, 2014 calculated in conformity with the SLR final rule, as described, to our SLR ratios calculated in conformity with applicable regulatory requirements as of the dates indicated.
